@vmprint/standard-fonts

StandardFontManager is a zero-asset FontManager that maps requested font families to the 14 standard PDF fonts and returns 5-byte sentinel buffers instead of real font data.

The engine detects each sentinel and uses built-in AFM metric tables rather than fontkit. Text measurement, line breaking, and pagination all work correctly — with no font files anywhere in the pipeline. The output PDF carries only PostScript font name references (e.g. /Helvetica-Bold); every conforming PDF viewer supplies the rendering for these fonts.

Usage

import { StandardFontManager } from '@vmprint/standard-fonts';
import { createEngineRuntime } from '@vmprint/engine';

const runtime = createEngineRuntime({ fontManager: new StandardFontManager() });
Copy

No configuration required.

When to use

• Font-free PDFs — output that uses only PDF-14 standard fonts, with no embedded binary font data
• Bundle-size-sensitive environments — edge functions, single-file CLIs, static HTML renderers
• Test pipelines — correct layout metrics without needing bundled font files

Alias mapping

Weight and style variants (bold, italic) resolve to the correct PostScript variant within each family.

Limitations

• Latin scripts only. Coverage is Windows-1252 (Latin-1 + Western European supplement). Characters outside this range render as missing glyphs.
• No kerning. AFM tables do not include kern pairs.
• No CJK or multilingual fallback. Use @vmprint/local-fonts for multilingual documents.
